What else can I help you with?
A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surfaceWhat will be the angle of reflection?
The angle of reflection is equal to the angle of incidence. It will be at 30o to the surface of the mirror (from the opposite edge) ^ This answer is not correct for SURFACE, but is correct for RELATIVE ^
Does distance of an object affects the size of reflection in a mirror?
Yes. This can be proven with the Law of Reflection. What this states is: the angle of incidence equals the angle of reflexion. For information about the law of reflection you can visit this site and review the diagrams and notes: http://www.glenbrook.k12.il.us/gbssci/phys/class/refln/u13l1c.html
When measuring the angle of incidence and the angle of refraction the imaginary line drawn perpendicular to the surface at the point of incidence is called the?
normal
What is the incidence angle at which the angle of refraction is 90 degrees called?
A right angle.
What is the critical angle of glass?
When light in glass of index of refraction n hits the surface at angle A relative to the surface normal (perpendicular line to the surface) it generally exits into the air at larger angle B. These three variables are related by Snell's Law: n Sin(A) = (1)Sin(B) (air has index of refraction approx. = 1 ) The critical angle A for internal reflection occurs when the exit angle is 90 so the exit light skims the surface. Anything larger then critical A and the light gets reflected back into the glass. So in Snell's law let B = 90; nSin(A) =(1)Sin(90) = (1)(1) so Sin(A) = 1/n For glass n ~ 1.5 so Sin(A) ~ .67 This is the sine of the critical angle. Now figure out what angle has a sign of .67 and Whala you have it.
According to the law of reflection if the angle of incidence is 45 degrees what is the angle of reflection?
If the angle of incidence is 45 degrees, then the angle of reflection will also be 45 degrees. This is because the angle of incidence is always equal to the angle of reflection according to the law of reflection.
When the angle made by the incidence ray and the reflection ray is 45 degree find the product of the angle of incidence and angle of reflection?
506.25
When light is reflected is the angle of incidence at right angles to the angle of reflection?
Not usually. (Only when the angle is 45 degrees.)"The angle of incidence is equal to the angle of reflection."
What happens to the angle of reflected light rays as the angle of incident light rays becomes steeper?
The angle of incidence equals the angle of reflection. Therefore, if your angle of incidence is 15 degrees, your angle of reflection equals that also. If it is 45 degrees, your angle of reflection is also 45 degrees, and so on.
Why angle of reflection 45 degree when angle of incidence is 90 degree when a ray is reflected?
The angle of reflection being 45 degrees when the angle of incidence is 90 degrees is a misunderstanding of the basic principles of reflection. According to the law of reflection, the angle of reflection is always equal to the angle of incidence, measured from the normal (the imaginary line perpendicular to the surface at the point of incidence). Therefore, if the angle of incidence is 90 degrees relative to the normal, the angle of reflection would also be 90 degrees, indicating that the ray reflects back along the same path.
The angle of reflection is equal to the .......?
The angle of incidence
When is angle of incidence equal to angle of reflection?
The angle of incidence is ALWAYS equal to the angle of reflection! This is one of the laws of reflection.
Does the relationship between the angle of incidence and the angle of reflection change as the angle of incidence increases?
No, the relationship between the angle of incidence and the angle of reflection remains the same regardless of the angle of incidence. This relationship is governed by the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
How does the change in the angle of incidence affect the angle of reflection?
The angle of reflection is equal to the angle of incidence. When the angle of incidence changes, the angle of reflection will also change accordingly, maintaining the law of reflection.
What is the size of the angle of incidence and reflection?
The size of the angle of incidence is equal to the size of the angle of reflection. This is known as the law of reflection, where the angle of incidence is measured between the incident ray and the normal, and the angle of reflection is measured between the reflected ray and the normal.
What happens to the angle of reflection when the angle of incidence decreases?
When the angle of incidence decreases, the angle of reflection also decreases. This relationship follows the law of reflection, which states that the angle of incidence is equal to the angle of reflection. As the angle of incidence becomes smaller, so does the angle of reflection in relation to the perpendicular line.
What is angle of incidence and angle of reflection mean?
The angle of incidence is the angle between the incident ray and the normal to the surface at the point of incidence. The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of reflection. According to the law of reflection, the angle of incidence is equal to the angle of reflection.
